The Company does not intend to sell, and it is unlikely that it will be required to sell the investments in an unrealized loss position prior to their anticipated recovery. The investments are high-quality U.S. treasury securities and the decline in fair value is largely due to changes in interest rates and other market conditions with the fair value expected to recover as they reach maturity. There were no other-than-temporary impairments for these securities during the three months ended March 31, 2024 and April 2, 2023.
